FEATURES AND APPLICATIONS The Model 6500 Multi-Purpose Sample Gas Conditioning System delivers representative, clean and dry sample to the analyzer in a cost effective method. Normally, 80% of the analyzer system problems are attributed to inadequate sample system components and design. Today, most companies are operating with limited resources for design and maintenance of the sample system. The Model 6500 incorporates the highest quality components and flexibility in design for reliable and trouble-free operation. Most gas analyzers require the sample stream to be free of solids and suspended liquids. The solid particulate and suspended liquid can block the sample passage to the analyzer. The suspended liquid can react with the sample stream resulting in an erroneous reading from the analytical instrument. The Model 6500 removes solid particulate and the suspended liquid ensuring the highest mean time between failure. The system consists of: Sample pump module Sample gas conditioning module Each of these modules can be used independently or they can be combined to provide a complete system. The above modules can also be used in combination with other sample system modules manufactured by Emerson. SAMPLE PUMP MODULE The pump module consists of diaphragm pump with stainless steel pump heads. The compact pump design uses a non-contaminating Teflon® diaphragm and leak-free check valves. Single and dual-head pumps are available depending upon the sample travel distance and the sample flow rate required. The pump is designed as a combination vacuum and pressure pump so the gas stream can be either pushed or pulled through the pump. It is available for 115 VAC or 230 VAC operation. Figure 1 shows the performance curves for each pump design which helps in selection of the most appropriate pump for a given application. A 60 micron particulate filter and a relief valve assembly is included with the pump to provide clean sample and to prevent over-pressurization or damage to the analyzer(s). An optional sample shut-off valve can be provided to isolate the system for maintenance purposes. Two mounting configurations are available when the sample pump module is purchased by itself. Horizontal plate - the pump can be mounted on a horizontal plate with mounting holes. The plate can be bolted on the floor or a shelf of a cabinet Wall-mount bracket - the pump can be mounted on a bracket with mounting holes. The bracket is suitable for wall-mounting SAMPLE GAS CONDITIONING MODULE Our rugged and dependable sample gas conditioning module is unique in the industry because it provides the most economical method for removing particulate and moisture from the sample stream. A 60 micron particulate filter is included with various moisture removing devices. For sample containing less that 2% moisture, a phase separator can effectively dry the sample. In the event moisture concentration is higher, a thermoelectric water condenser is recommended. This unique peltier cooler based heat exchanger does not use freon or a compressor, and it effectively dries the sample up to a dew point of 40°F (5°C). An optional moisture sensor is available to detect any excess moisture carry-over. A peristaltic pump is provided for continuous removal of the condensed moisture. For precautionary purposes, a 1-micron coalescing filter can also be included to remove any additional moisture droplets created by the compression of the sample gas in the diaphragm pump. In the event of moisture carry-over, alarm relays can be used to shut off the sample pump, preventing damage to the analyzer. An optional sample shut-off valve is available to isolate the sample system, which facilitates maintenance work on the analytical system, which facilitates maintenance work on the analytical system. The complete sample gas conditioning module is mounted on a 19” backplate which is suitable for rackmounting. It can also be provided with brackets for wallmounting configuration. When the sample pump is purchased in conjunction with the sample gas conditioning system, all the components, including the pump, are mounted on a back plate suitable for mounting on a 19” rack. Brackets can be provided for wall-mounting configuration. It is available for 115 VAC or 230 VAC operation.
